| Abstract | Experimental research suggest that even when sowed after soybean harvest, out-of-season corn yield can be increased with nitrogen sidedressing fertilization. However, doubts still exist about nitrogen source and dose for corn in the growing modality. The objective of this work was to evaluate the effect of sources and doses of sidedressed nitrogen application on out-of-season corn, grown after soybean crop. A randomized complete block design in a 2 x 4 factorial scheme, with four replications was used. Treatments were constituted by two sources (urea and ammonium sulfonitrate with nitrification inhibitor – Entec 26) and four doses (0, 30, 60, and 120 kg ha) of N, applied when the plants presented four expanded leaves. Sidedressing nitrogen application increased plant and first ear insert height, number of grains per ear, and grain yield of out-of-season corn grown in no-tillage system, after soybean crop. High doses of nitrogen (120 kg ha), applied as ammonium sulfonitrate, provided larger plant and first ear insert http://dx.doi.org/10.18512/1980-6477/rbms.v5n3p395-405 |
